Remember that Chinese sourced TI clock chip that we decapped with Antoine? Not fake at all tells me Ken Shirriff. But does it actually work? It sure did not when I put it on my HP board. One simple way to find out. Chinese sourced TI chip, 1970's HP bubble LED, proto board, and a bit of fun reverse engineering as this chip is completely undocumented. 2.5V power, kooooontakt! Result is beautifully vintage! Video should be out soon.
